I. Overview:The Rock Electric Direct Shear Tester is developed in accordance with the national industry standards (SL264-2001) "Code for Rock Testing of Hydraulic and Water Conservancy Engineering Projects" and (JTG E41-2005) "Code for Rock Testing of Highway Engineering Projects". The instrument employs the flat push method and is mainly suitable for direct shear tests on rock blocks, structural surfaces (such as joint planes, bedding planes, foliation planes, and fissure planes), and the contact surfaces (bonding surfaces) between concrete (or mortar) and rock. It is also used for shear strength tests on the bonding surfaces between concrete and other materials. The machine features a simple structure, light weight, intuitiveness, easy maintenance, and can be used in the field. The test data is displayed digitally, ensuring accuracy and reliability.
